GATE.

SPECIFICATION forming part of Letters Patent No. 380,232, dated March 27, 1888-4 Application led January 13, 1868. Serial N o. 260.655. (No model.) I

To all whom ibm/wg] concern:

13e it known that I, HARLAN P. WALKER, a citlzen of the United States, and a resident of Boulder, in the county of Boulder and State of 5 Colorado, have invented certain new and useful Improvements in Gates; and Ido hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it apro pertains to make and use the same,reference belng had to theaccompanying drawings, whIch form a part of this specification, and in whioh-` Figure ll'is a perspective view of my new I5 and improved gate. Fig. 2 is a side view of thesame, showing the gate closed. Fig. 3 is aside view showing the gate opened. Fig. 4 1s a detail of the double main post, and Fig. 5 is a detail view of the rear end post. 2o The same numerals of reference indicate corresponding parts in all the figures.

My invention consists in a new and im proved sliding gate, which is especially designed as a farm or road gate, and which can 25 be opened and closed from either side without dismounting from horseback or from a vehicle,

and .my lnventiou will be hereinafter fully described and claimed.

Referring to the several parts by their des 3o 1gnat1ng-numerals, 1 indicates the gate proper,

and 2 indicates thedouble main post throughwhich the'gate slides. This gate 1 is of a reetangular shape, with a strong top rail, 3, along the lower edge of which is secured a half-round 3 5 bar of iron, 4, which runs in the grooved roll ers hereinafter referred to, and thus prevents wear of the top rail itself. The double post 2 l is formed with the two parallel side pieces, 2a.

2a, whichare connected at their upper ends by 4o the short topA piece, 2". y

The top rail of the gate passes through and 1s supported in a metal stirrup, 5, the halfround iron with which the lower edge of the said top rail is shod running in a grooved 45 roller, 6, which is journaled in the lower contracted part ofthe stirrup. This stirrup is supported by a rope, 7, which is secured at one end to a hook, 8, at the top of the stirrup, then passes up and over a grooved pulley, 5o 9, which is journaled in a slot, 10, in one of the side pieces, 2, and to the lower end of vthis rope is secured a large weight, 11, which is of sufficient size to overbalance the weight ofthe gate and hold -the same up out of contact with the ground. 'To'. the lower end of the stirrup is secured a stop or guide bar, 12, the ends of which extend through and play in vertical slots 13 13, which are formed in the side pieces of the post 2, this cross bar or guide, while permitting a certain amount of 6o movement or play to the stirrup, always hold'- ing it in proper position and preventing its working out from betweenr the sides of the double post 2.

'rhe- 'front ena 0f the gamas provided with 65 a latch, 14, which, when the gate is closed,. engages with a recess, 15, in the latch-post 16 in the usual manner, and inthe lower end of the front upright, 17, of the gate is journaled a'roller, 18, which causes thefront end of the gate to pass readily over. the ground when it swings' down in opening or closing the gate.

Thetop rail, 3, of the gate projects back at the rear end, of the gate for a distance slightly v greater than the length of the gate proper, and 7 5 from the lower end of the rear upright, '19of the gate an inclined brace, 20, extends up until its rear end vmeets the rear end of thefrail 3, where the two are bolted securely together. rlhe half-round bar of iron 4 extends under the entire length of the upper rail, 3. A guide-post, 21, is secured in the ground back of the main post 2 at a distance equal to the length of the gate itself, and to one side of this guide-post is secured a bracket, 22,in the lower and upper portions of which are journaled the two grooved rollers 23 23. The rearwardly-extending part of the top rail, 3, lruns through this bracket between the said two rollers, and it will beseeu that this guide- 9o post will serve to steady and guide the gate when the latter is being opened and closed.

'lhe double main post. is secured in the ground at the side of the road, and from the top of this postextend on each side the oppo- 9 5 site horizontal beams 24 24,which are secured at their outer ends upon the* upper ends of vertical posts 25 25, secured in the ground at asuitable distance on each side of the main double post 2. Inclined braces 26 26 are se- Ioo cured at their upper ends to. the horizontal beams 24 near the outer ends of thesame, andv then incline down and out, and are bolted against the uprights 25 25, as shown. Upon each inclined brace are pivoted or journaled two grooved rollers or pulleys, 27 and 28, and to the outer opposite edges of each side piece of the double post 2 are attached the

grooved pulleys

29 and 30. On each side of the gate is arranged an operatiugrope, 3l, for opening and closing the gate, each rope being secured at one end to the top of the front end of the gate, then passing through the pulley 29 at that side of the main post 2, then up and over the pulley 27 on the inclined brace 26, then down through a pulley, 32, hereinafter referred to, then up and over a pulley, 28, down through the pulley 30, and is finally secured at its other end to the top of the rear' end of the gate proper. Each of the pulleys 32 is secured to the top of a weight, 33, which has an eye, 34, which slides upon aguide-rod, 35, secured at its ends to the upright 25.

In order to open the gate the traveler, appreaching the gate from either side,pullsupon that part of the. operating-rope which runs through thepulley 29, whenthe gate will berapidly rol-led back to its. open position, while to close the gate the other part of the operatingrope, which runs through the pulley 30, is pulled upon, when the gate will roll to into its closed position. It will be seen that as the gate is thus rolled or pulled back and forth to open and close it it will run easily in the grooved rollers of the stirrup` and guide-post, the weight of thegate resting mainly upon the weighted stirrup, so that the friction is reduced to the lowest point. When the gate is being opened and reaches a point where the weight 11 is heavier than will overbalance the weight of the frontendv ofthe gate,the center of gravity of the gate will be changed,its front end will rise up, and the gate will run back by force of gravitation. In the same manner, when the gate is being closed, as soon as its front end becomes heavier than the weight 11 the center of gravity will be again changed and the front end of the gate will-drop and the gate will close by force of gravity.

It will be seen that owing to this peculiar construction and arrangement of parts the gate will be to a certain extent automatic, and that it can consequently be opened and closed with a very slight pull on the operatingrope. The operating ropes are prevented from kinkiug or twisting up by the weights 33, and by arranging the weights to slide on theguide-rods 35 the weight will adjust itself to the contraction and elongation of the operating-ropes caused by the changes of atmosphere, the alternating moisture and dryness.

Instead of the precise form of bracket shown at the guide-post any other suitable form or means for effecting the same purpose may be substituted. s

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. The combination, with the sliding gate, of a counterbalanced stirrup, arranged substantially as set forth.

2. The combination, with the sliding gate, of the double post having the grooved roller journaled in its upper end,l a stirrup through which the top rail of the said gate slides, and the rope secured at one end to the said stirrup, passing over the grooved roller, and having the weight at its other end, substantially as set forth.

3. The combination, with thesliding gate, of the double post formed with the opposite side slots and having the grooved roller journaled in its upper end, the stirrup having the roller journaled in its lower portion andthe guide-bar secured to its lower end, the weightcord, and the weight, substantially as set forth.

4. The combination, with the sliding gate having the metal shoe or rod secured along the lower edge of its top rail, of the double postformed with the opposite side slots and4 having the grooved roller journaled in its upperend, the stirrup having the grooved roller journaled in4 its lower portionV and the guidebar secured to its lower end, the weight-cord, and the weight, substantially as set forth. 5. The combination, with the sliding gate formed with the rearwardly-extended top rail and the rear inclined brace and having the metal shoe secured along the lower edge of the said top bar, of the guide-post, the bracket secured to the same and having. the rollers journale'd within it, the double post formed with the opposite side slots and having the grooved roller journaled in its upper end, the stirrup having the grooved roller journaled in its lower portion and the guide-bar secured to its lower end, the weight-cord, and the weight, substantially as set forth.

6. The combination, with the sliding gate, ofthe operating-ropes, the pulleys for the same attached to the double post and to the inclined braces 26 26, the weights having the pulleys at their upper ends and the side eyes, and the guide-rods, al1 arranged substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereunto aixed my signature in presence of two witnesses.
